Shaneee Posted July 6, 2023 Share Posted July 6, 2023 (edited) First real dive into the Intel side of things. I've got a Dynabook (Toshiba) A40-G-138. It has a 10210u and what I can tell UHD 620. I've setup the device properties and can boot into Ventura without issue. I did have an issue where the backlight didn't initialise when it should and took a good 3-5 minutes for the display to turn on. As I've said though I got that fixed but now I'm facing that issue again with Sonoma. Same EFI but with some Sonoma tweaks for kexts, mainly for itlwm. iGPU properties haven't been touched. The system currently triple boots Windows 11, Ventura and Sonoma. Sonoma for testing out before updating Ventura. Here's the current properties that work without issue on Ventura but have that backlight delay on Sonoma. Don't judge too harshly if none of this is actually needed Thanks in advance Edit: I've found the fix. I needed to add enable-backlight-registers-alternative-fix along with what I had there and now Sonoma boots right to the login screen. Edited July 6, 2023 by Shaneee Found a solution. 1 Link to comment Share on other sites More sharing options...
